Nike Vapor Fly Pro iron set with 8 clubs, which includes 3-iron through 9-iron and a pitching wedge. These clubs are brand new and right handed. The shafts are custom installed Rifle Project X 5.5 steel. If you are familiar with Project X shafts then you know that their numbering system does not precisely correlate to a specific flex, but 5.5 is essentially regular flex. Grips are black and gold Z Grips, made by Golf Pride just for Nike. These irons offer tour-preferred forgiveness and distance in a modern muscle design. The NexCOR faces generate consistently fast ball speed. You'll love the Vapor Fly Pro irons for many rounds to come.
